"I have always admired and had enormous respect for Elizabeth Taylor," Lohan, 25, said in a statement. "She was not only an incredible actress but an amazing woman as well. I am very honored to have been asked to play this role."

"What a relief. I didn't have to check the toilet for anything or the light bulbs or the phone," she says of the on-set pranks by her Oceans Twelve pals. "It was just good old-fashioned friendship."

And fun. Roberts, 41, returns to the big screen in the romantic caper Duplicity, in theaters March 20, reuniting with her Closer costar Owen. She says Owen, 46, makes her laugh constantly, which helped sparked instant chemistry onscreen.

"We have a similar sense of humor," she says. "Our list of priorities in our personal lives are not different. We are both happily married with families and lead a pretty normal, unaffected existence within in this odd universe of show business that we've both chosen to go into."

Clive Owen can boast plenty of beautiful costars – from Angelina Jolie in Beyond Borders, Julia Roberts in Closer and Jennifer Aniston in Derailed to Monica Bellucci in the upcoming Shoot 'Em Up – but the married star says he'd never have an affair with a costar.
